Technical description

Cells management

  • Master/Slave architecture
  • Possibility to connect up to 20 CMC in series to manage a battery pack with a voltage up to 1000 Volts
  • Possibility to connect up to 7 BMC in parallel thanks to an EMS
  • Management from 5 to 12 cells in series per CMC, compatible with all cell technologies (NMC, Na Ion, LFP, LTO…) :
    o NMC/Na Ion : From 5S to 12S*
    o LFP : From 6S to 12S*
    o LTO : From 8S to 12S*
  • +/- 2 mV of accuracy
  • Management of 4 NTC temperature sensors per CMC


  • Overcharge and undercharge, tunable by software
  • Overcurrent and over/under temperature, tunable by software
  • Designed following ISO26262, equivalent ASIL B

Power box

  • Bidirectional measurement of the battery current with a hall effect sensor
  • Charge and discharge management
  • Command up to 4 external electromechanical contactors
  • Command up to 2 current sensors

Smart functions

  • SOC and SOH calculation
  • Advanced self-diagnostic of the board
  • Communication by 2 CAN bus 2.0B (opto-isolated)
  • Calculation of max charge and discharge current allowed.
  • Insulation measurement through an external board (bender)
  • Black box integrated with faults history storage and life counters
  • Possibility to modify the parameters (cells characteristics, alarms thresholds…) using the Supervision software
  • Passive balancing with a 150mA bypass current per cell

Spare IO (function can be customized)

  • 2 High Side outputs
